技术领域technical field

本实用新型关于一种摩托车,特别是指一种具有变速机构的摩托车。The utility model relates to a motorcycle, in particular to a motorcycle with a speed change mechanism.

背景技术Background technique

参阅图1,为一种已知的驱动盘组件11,设置于一车体(图未示)上。该驱动盘组件11包括一适用于固定在该车体上且围绕一轴线L1而呈环状的第一固定盘111、一由该第一固定盘111的内周缘沿该轴线L1延伸且围绕界定出一供一引擎曲轴(图未示)穿设的容置空间10的环套112、一可滑动地套设于该环套112的滑动盘113、一适用于固定在该车体上且连接该环套112并与该滑动盘113相间隔的第二固定盘114,及多个设置于该第一固定盘111与该滑动盘113之间而沿该轴线L1的方向顶抵该第一固定盘111与该滑动盘113,并沿径向方向移动的滚珠115。该滑动盘113具有多个面向该第一固定盘111,且与该第一固定盘111相配合界定出多个分别供该等滚珠115滚动的容槽110的弧面116。依照周向方向的视角观点,该等弧面116如图1所示地呈圆弧状,且具有相同的曲率半径。Referring to FIG. 1, it is a known drive disk assembly 11, which is arranged on a vehicle body (not shown). The drive plate assembly 11 includes a first fixed plate 111 adapted to be fixed on the vehicle body and in an annular shape around an axis L1, a first fixed plate 111 extending along the axis L1 and defined around the inner circumference of the first fixed plate 111 A ring sleeve 112 of the accommodating space 10 for an engine crankshaft (not shown) to pass through, a sliding plate 113 slidably sleeved on the ring sleeve 112, a ring sleeve 113 suitable for being fixed on the vehicle body and connected The ring sleeve 112 and the second fixed plate 114 spaced apart from the sliding plate 113, and a plurality of second fixed plates 114 disposed between the first fixed plate 111 and the sliding plate 113 and abutting against the first fixed plate along the direction of the axis L1 The disc 111 and the sliding disc 113 and the balls 115 move in the radial direction. The sliding plate 113 has a plurality of arc surfaces 116 facing the first fixed plate 111 and cooperating with the first fixed plate 111 to define a plurality of cavities 110 for the balls 115 to roll respectively. According to the viewing angle in the circumferential direction, the arc surfaces 116 are arc-shaped as shown in FIG. 1 and have the same radius of curvature.

该引擎曲轴可带动该驱动盘组件11以该轴线L1为转轴转动,当转速较低时,该等滚珠115产生的离心力较小,而沿着该等弧面116往径向方向愈邻近该轴线L1,并使该滑动盘113邻近该第一固定盘111,而使该滑动盘113与该第二固定盘114的间距变大,进而使设置于该滑动盘113与该第二固定盘114之间的一皮带12沿径向方向往内缩而邻近该轴线L1,借此达到低档位,高减速比的状态。当转速较高时,该等滚珠115离心力较大,而沿着该等弧面116往径向方向愈远离该轴线L1,并推挤该滑动盘113而使该滑动盘113相对于该第一固定盘111往该轴线L1的方向移动,也势必让该滑动盘113与该第二固定盘114的间距变小,进而使该皮带12沿径向方向往外扩而远离该轴线L1,借此达到高档位,低减速比的状态。The engine crankshaft can drive the drive plate assembly 11 to rotate around the axis L1. When the rotational speed is low, the centrifugal force generated by the balls 115 is small, and the radial direction along the arc surfaces 116 is closer to the axis. L1, and make the sliding plate 113 adjacent to the first fixed plate 111, so as to increase the distance between the sliding plate 113 and the second fixed plate 114, and then make the distance between the sliding plate 113 and the second fixed plate 114. A belt 12 between them shrinks inward in the radial direction and is adjacent to the axis L1, thereby achieving a state of low gear and high reduction ratio. When the rotational speed is high, the centrifugal force of the balls 115 is large, and the balls 115 are farther away from the axis L1 in the radial direction along the arc surfaces 116, and push the sliding plate 113 to make the sliding plate 113 relative to the first When the fixed plate 111 moves in the direction of the axis L1, the distance between the sliding plate 113 and the second fixed plate 114 is bound to become smaller, so that the belt 12 expands outward in the radial direction away from the axis L1, thereby achieving High gear, low reduction ratio state.

然而,该等弧面116呈单一曲率半径的设计,调整的变数较少,容易产生某段贴合变速需求,其他段则偏离变速需求的问题,因而仅能符合特定的变速区域,或是完全不符合变速需求,也就是说,适用性较差而无法满足较大范围且精准的变速需求。举例来说,该等弧面116沿径向方向愈往内而愈平坦,导致该等滚珠115的推动该滑动盘113的幅度较小,使得该皮带12沿该径向方向往外扩的幅度较小,以至于摩托车起速较为缓慢。相反地,该等弧面116沿径向方向愈往外而愈陡峭,导致该等滚珠115推动该滑动盘113的幅度较大,使得该皮带12沿径向方向往外扩的幅度突然变大,以至于变速曲线变化较大而容易发生危险,因此上述缺点有待改善。However, the arc surfaces 116 are designed with a single radius of curvature, and there are few adjustment variables, and it is easy to cause a problem that certain sections meet the shifting requirements, while other sections deviate from the shifting requirements, so they can only meet a specific shifting area or completely It does not meet the shifting needs, that is to say, the applicability is poor and cannot meet the needs of wider and precise shifting. For example, the arc surfaces 116 are flatter as they go inward in the radial direction, so that the balls 115 push the sliding plate 113 to a smaller extent, so that the belt 12 expands outward in the radial direction. So small that the motorcycle starts slowly. On the contrary, the arc surfaces 116 become steeper as they go outward in the radial direction, which causes the balls 115 to push the sliding plate 113 to a greater extent, so that the belt 12 expands abruptly to the outside in the radial direction. As for the change of the speed change curve, it is easy to be dangerous, so the above shortcomings need to be improved.

In this embodiment, the first fixing plate 421 is preferably a pressure plate, and is fixed on the driving mechanism 3 , but not limited to this, as long as there is no relative movement between the driving mechanisms 3 . The sliding plate 423 has a plurality of arc surfaces 426 facing the first fixed plate 421 and cooperating with the first fixed plate 421 to define a plurality of accommodating grooves 420 for the balls 425 to move respectively, and an opposite to the The arc surface 426 faces the second fixed plate 424 and is in contact with the outer ring surface 427 of the speed change transmission member 44 . Wherein, the arc surfaces 426 surround the axis L2 at intervals in a radial shape, so that the balls 425 are evenly arranged on the sliding plate 423 to achieve better rotational stability. The outer annular surface 427 gradually expands and extends in the radial direction along the direction away from the second fixing plate 424, and is inclined to the axis L2.

特别需要说明的是,在以周向方向的视角观点下,每一个弧面426由两个沿径向方向依序衔接,且曲率半径互不相同的滚动线段S所构成。在本实施例中,每一个弧面426的靠近该轴线L2的该滚动线段S的曲率半径,小于远离该轴线L2的该滚动线段S的曲率半径,但不以此为限,只要相邻的两个滚动线段S的曲率半径互不相同即可。在每一个弧面426中,定义一位于相邻两个滚动线段S的衔接处的切线L3,该切线L3为该等滚动线段S的公切线,使得该等滚动线段S之间无段差,可确保变速的连续性,以及避免该等滚珠425卡住而发生变速问题,进而提升耐久性。本实施例不以每一个弧面426中该等滚动线段S的数量为限,亦可为每一个弧面426是由至少三个滚动线段S所组成,且形成至少两个公切线。其中,相邻的两个滚动线段S的曲率半径互不相同,且每一个弧面426的该等滚动线段S的曲率半径,沿径向方向远离该轴线L2逐渐变大。再者,最靠近该轴线L2的该等滚动线段S的曲率半径,比沿径向方向远离该轴线L2的该等滚动线段S的曲率半径还要小,即可达成本案的功效。It should be particularly noted that, from the perspective of the circumferential direction, each arc surface 426 is formed by two rolling line segments S that are connected in sequence along the radial direction and have different radii of curvature. In this embodiment, the radius of curvature of the rolling line segment S close to the axis L2 of each arc surface 426 is smaller than the radius of curvature of the rolling line segment S far from the axis L2, but not limited to this, as long as the adjacent The radii of curvature of the two rolling line segments S only need to be different from each other. In each arc surface 426, a tangent L3 is defined at the junction of two adjacent rolling line segments S, and the tangent L3 is the common tangent of the rolling line segments S, so that there is no step difference between the rolling line segments S, which can be It ensures the continuity of shifting, and avoids shifting problems caused by the balls 425 being stuck, thereby improving durability. In this embodiment, the number of the rolling line segments S in each arc surface 426 is not limited, and each arc surface 426 may also be composed of at least three rolling line segments S and form at least two common tangents. The curvature radii of the two adjacent rolling line segments S are different from each other, and the curvature radii of the rolling line segments S of each arc surface 426 gradually increases away from the axis L2 in the radial direction. Furthermore, the curvature radii of the rolling line segments S closest to the axis L2 are smaller than the curvature radii of the rolling line segments S farther from the axis L2 in the radial direction, so that the effect of the present solution can be achieved.

该从动盘组件43设置于该壳体41内,且具有二可调整彼此间距的从动盘431,及一与该驱动轴32并排且穿设于该等从动盘431,并连接该齿轮组件46而用以驱动该传动轴45转动的从动轴432。其中,为了方便说明,定义一通过该从动轴432的轴心的轴心线C3,及一沿该左右方向D2延伸且与该从动轴432的该轴心线C3并排,并通过该从动盘431沿该前后方向D1靠近该轴线L2的前缘的辅助线C4。每一个从动盘431具有一朝向另一从动盘431,且往另一从动盘431的方向渐缩的内弧面433。特别需要说明的是,该从动轴432的该轴心线C3沿该前后方向D1至该辅助线C4的距离,大于该驱动轴32的该轴心线C1沿该前后方向D1至该辅助线C4的距离,进一步地提升该变速机构4的空间紧致性。The driven plate assembly 43 is disposed in the housing 41 and has two driven plates 431 with adjustable distances from each other, and a driven plate 431 parallel to the drive shaft 32 and passing through the driven plates 431 and connected to the gear The driven shaft 432 used to drive the transmission shaft 45 to rotate by the assembly 46 . Wherein, for the convenience of description, an axis line C3 passing through the axis of the driven shaft 432 is defined, and an axis line C3 extending along the left-right direction D2 and side by side with the axis line C3 of the driven shaft 432, and passing through the axis line C3 of the driven shaft 432 is defined. The moving plate 431 is close to the auxiliary line C4 of the leading edge of the axis L2 along the front-rear direction D1. Each driven disk 431 has an inner arc surface 433 that faces the other driven disk 431 and tapers toward the other driven disk 431 . It should be noted that the distance from the axis C3 of the driven shaft 432 to the auxiliary line C4 along the front-rear direction D1 is greater than the distance from the axis C1 of the driving shaft 32 to the auxiliary line along the front-rear direction D1 The distance of C4 further enhances the space compactness of the transmission mechanism 4 .

该变速传动件44较佳为传动皮带,但不以此为限。该变速传动件44沿该前后方向D1延伸,且设置于该滑动盘423的外环面427与该第二固定盘424间,及设置于该等从动盘431的内弧面433间。其中,该变速传动件44受到该驱动盘组件42的带动而转动,并同时传动该从动盘组件43转动,进而达到传动的功效。在本实施例中,配合倾斜的该外环面427、该第二固定盘424的外表面,以及该等内弧面433的倾斜设计,使得该变速传动件44能受到该滑动盘423的推挤,而沿该驱动盘组件42的径向方向往该轴线L2靠近或远离,并带动改变该等内弧面433的间距变小或变大,借此调整车速档位及减速比。The speed change transmission member 44 is preferably a transmission belt, but not limited thereto. The speed change transmission member 44 extends along the front-rear direction D1 and is disposed between the outer annular surface 427 of the sliding plate 423 and the second fixed plate 424 and between the inner arc surfaces 433 of the driven plates 431 . Wherein, the speed change transmission member 44 is driven by the drive plate assembly 42 to rotate, and at the same time drives the driven plate assembly 43 to rotate, thereby achieving the effect of transmission. In this embodiment, the inclined design of the inclined outer annular surface 427 , the outer surface of the second fixed plate 424 , and the inner arc surfaces 433 enables the speed change transmission member 44 to be pushed by the sliding plate 423 . squeeze, and move closer to or away from the axis L2 along the radial direction of the drive disk assembly 42, and drive the distance between the inner arc surfaces 433 to become smaller or larger, thereby adjusting the vehicle speed gear and reduction ratio.

其中,定义该驱动轴32的该轴心线C1沿该前后方向D1至该从动轴432的该轴心线C3的距离为一轴距W,该轴距W为130~150mm,较佳为145mm。受到市面上的产品规格影响,若该轴距W小于130mm时,该轴距W则会过短而产生该驱动盘组件42与该从动盘组件43的相互干涉问题。若要解决干涉问题,则要缩小该驱动盘组件42与该从动盘组件43的尺寸,势必会牺牲部分的变速特性,使得加速性变差。若该轴距W大于150mm时,该轴距W则会过长,势必会增长该变速传动件44的长度,而容易造成振动拍打的情况,另外也会增加该驱动机构3的尺寸与重量,并间接缩短该摇臂机构5的长度,导致操控性降低。而当该轴距W为145mm时,不仅能维持该驱动盘组件42与该从动盘组件43之间的变速特性,还能缩小该驱动机构3与该变速机构4的体积与重量,达到较佳的空间配置。另外需要说明的是,该从动轴432的该轴心线C3与该传动轴45的该轴心线C2相重合,在不影响传动性能下,进而减少该驱动机构3与该变速机构4的尺寸与重量,使得本实施例整体的结构更紧致。此外,该等从动盘431的后缘沿该前后方向D1位于该齿轮组件46的后缘的后方,进一步地提升车用空间以利其他元件装设,达到紧致化的功效。Wherein, the distance from the axis C1 of the drive shaft 32 to the axis C3 of the driven shaft 432 along the front-rear direction D1 is defined as a wheelbase W, and the wheelbase W is 130-150mm, preferably 145mm. Affected by the product specifications in the market, if the wheelbase W is less than 130 mm, the wheelbase W will be too short, resulting in the problem of mutual interference between the driving disk assembly 42 and the driven disk assembly 43 . In order to solve the interference problem, the size of the drive disk assembly 42 and the driven disk assembly 43 must be reduced, which will inevitably sacrifice part of the speed change characteristics, resulting in poor acceleration. If the wheelbase W is greater than 150mm, the wheelbase W will be too long, which will inevitably increase the length of the speed change transmission member 44, which will easily cause vibration and flapping, and also increase the size and weight of the drive mechanism 3. And indirectly shorten the length of the rocker arm mechanism 5, resulting in reduced controllability. And when the wheelbase W is 145mm, not only can the speed change characteristics between the drive plate assembly 42 and the driven plate assembly 43 be maintained, but also the volume and weight of the drive mechanism 3 and the speed change mechanism 4 can be reduced to achieve a higher optimal space configuration. In addition, it should be noted that the axis line C3 of the driven shaft 432 coincides with the axis line C2 of the transmission shaft 45, so as to reduce the distance between the drive mechanism 3 and the speed change mechanism 4 without affecting the transmission performance. The size and weight make the overall structure of this embodiment more compact. In addition, the trailing edges of the driven discs 431 are located behind the trailing edge of the gear assembly 46 along the front-rear direction D1 , which further increases the space for the vehicle to facilitate the installation of other components and achieves a compact effect.

该齿轮组件46较佳为湿式减速齿轮组,但不以此为限,能受该从动轴432驱动而带动该传动轴45转动,并使该传动轴45的转速不同于该从动轴432的转速。The gear assembly 46 is preferably, but not limited to, a wet reduction gear set, and can be driven by the driven shaft 432 to drive the transmission shaft 45 to rotate, and make the rotation speed of the transmission shaft 45 different from that of the driven shaft 432 speed.

该摇臂机构5包括二连接该后车轮6与该驱动机构3并可相对于该车体2上下摆动的摇臂件51,及一连接该传动轴45与该后车轮6,且可带动该后车轮6转动的挠性传动件52。本实施例不以所述摇臂件51的数量为限,亦可为一个摇臂件51。该挠性传动件52选自皮带或炼条其中一个,但不以此为限。The rocker mechanism 5 includes two rocker members 51 that connect the rear wheel 6 and the driving mechanism 3 and can swing up and down relative to the vehicle body 2 , and a rocker 51 that connects the transmission shaft 45 and the rear wheel 6 and can drive the The flexible transmission member 52 for the rotation of the rear wheel 6 . In this embodiment, the number of the rocker arm members 51 is not limited, and it can also be one rocker arm member 51 . The flexible transmission member 52 is selected from a belt or a chain, but is not limited thereto.

该后车轮6靠近该驱动机构3的前缘沿该前后方向D1位于该从动盘431的前缘与后缘之间,使得本实施例的整体空间结构更紧致。The front edge of the rear wheel 6 close to the driving mechanism 3 is located between the front edge and the rear edge of the driven plate 431 along the front-rear direction D1, so that the overall spatial structure of this embodiment is more compact.

参阅图3、图4与图6,当该驱动轴32的转速从零开始提升时,该等滚珠425会收到离心力的影响,分别沿着该等弧面426往该滑动盘423的径向方向地向外移动。由于每一个弧面426的邻近该轴线L2的该滚动线段S的曲率半径较小以呈现较大的弯曲度,而沿径向方向往外较为陡峭,使得相对应的该滚珠425往径向方向移动的同时,沿该左右方向D2的移动幅度较大,并推抵该滑动盘423沿该轴线L2往该第二固定盘424的方向大幅地移动,以快速地缩小该滑动盘423与该第二固定盘424的间距,借此使该变速传动件44沿该滑动盘423的径向方向外扩,便能快速地提升档位而有较佳的加速性,并能避免起速过慢的问题发生。接着,当该驱动轴32的转速较高时,每一个滚珠425通过相对应的该弧面426的靠近该轴线L2的该滚动线段S,且开始在该弧面426的远离该轴线L2的该滚动线段S上移动。由于每一个弧面426远离该轴线L2的该滚动线段S的曲率半径较大以呈现较小的曲率,而沿该滑动盘423的径向方向较为平缓,使得相对应的该滚珠425往径向方向移动的同时往该左右方向D2的移动幅度较小,导致该滑动盘423沿该轴线L2的移动幅度也较小,势必也缓和该变速传动件44沿该滑动盘423的径向方向外扩的速度,借此调整变速曲线,并能降低油耗。因此,借由不同曲率半径的该等滚动线段S,使得本实施例能匹配高速与低速所需要的推力与加速需求,进一步地提升变速能力。Referring to FIG. 3 , FIG. 4 and FIG. 6 , when the rotational speed of the drive shaft 32 starts to increase from zero, the balls 425 are affected by centrifugal force, and move along the arc surfaces 426 to the radial direction of the sliding plate 423 respectively. move outwards in a direction. Since the radius of curvature of the rolling line segment S adjacent to the axis L2 of each arc surface 426 is relatively small to exhibit a large curvature, and is relatively steep outward in the radial direction, the corresponding ball 425 moves in the radial direction At the same time, the moving range along the left-right direction D2 is relatively large, and pushes the sliding plate 423 to move greatly along the axis L2 toward the second fixed plate 424, so as to rapidly shrink the sliding plate 423 and the second fixed plate 424. By fixing the distance between the discs 424, the speed change transmission member 44 can be expanded outward along the radial direction of the sliding disc 423, so that the gear can be quickly increased to have better acceleration and avoid the problem of too slow starting speed. occur. Next, when the rotational speed of the drive shaft 32 is high, each ball 425 passes through the rolling line segment S of the corresponding arc surface 426 close to the axis L2, and starts at the arc surface 426 away from the axis L2. Scroll line segment S to move. Since each arc surface 426 has a larger radius of curvature of the rolling line segment S away from the axis L2 to exhibit a smaller curvature, and is relatively gentle along the radial direction of the sliding plate 423 , the corresponding balls 425 move radially When the direction moves, the moving range in the left-right direction D2 is small, resulting in a small moving range of the sliding plate 423 along the axis L2, which is bound to ease the outward expansion of the speed change transmission member 44 along the radial direction of the sliding plate 423. speed, thereby adjusting the shifting curve and reducing fuel consumption. Therefore, by means of the rolling line segments S with different curvature radii, the present embodiment can match the thrust and acceleration requirements required by high speed and low speed, thereby further improving the speed change capability.

特别需要说明的是,市面上的产品若缩短该轴距W,虽能获致该变速机构4的相关尺寸紧致化,但容易影响变速性能而产生诸多问题,例如:起步加速时,该驱动盘组件42施于该变速传动件44的夹持力不足,而容易造成该变速传动件44打滑或起步反应性迟缓等问题。相反地,当加大对该变速传动件44的夹持力设定时,虽然能克服前述起步加速时所产生的问题,但却发生在中速或高速时该变速传动件44的夹持压力负荷过大,导致该变速传动件44的结构受损而容易断裂,或高速时加速反应性迟钝等。因此,为了克服上述问题,本实施例才需要借由该等弧面426所产生的多曲率半径变速特性,借此多段式地调整该驱动盘组件42与该变速传动件44之间的连动关系,以满足不同的加速需求。具体来说,当本实施例处于低速时,配合每一个弧面426的曲率半径较小的该滚动线段S,借此大幅度地推动该滑动盘423而产生较大的起始推力,进而增加对该驱动盘组件42的夹持力,达到快速起步,且提升变速反应性。当本实施例达到中速或高速时,配合每一个弧面426的曲率半径较大的该滚动线段S,借此缓和该滑动盘423的移动而有较适当的加速性能,且能减少部件磨耗与油耗,进而增加耐久性。It should be noted that, if the product on the market shortens the wheelbase W, although the relevant dimensions of the speed change mechanism 4 can be compacted, it is easy to affect the speed change performance and cause many problems. The clamping force exerted by the assembly 42 on the speed change transmission member 44 is insufficient, which may easily cause problems such as slippage of the speed change transmission member 44 or sluggish starting response. Conversely, when the setting of the clamping force of the speed change transmission member 44 is increased, although the aforementioned problems caused by starting acceleration can be overcome, the clamping pressure of the speed change transmission member 44 occurs at medium or high speed. If the load is too large, the structure of the speed change transmission member 44 will be damaged and easily broken, or the acceleration response will be slow at high speed, and the like. Therefore, in order to overcome the above problems, the present embodiment only needs to use the multi-curvature radius speed change characteristics generated by the arc surfaces 426 to adjust the linkage between the drive plate assembly 42 and the speed change transmission member 44 in multiple stages. relationship to meet different acceleration needs. Specifically, when the present embodiment is at a low speed, the rolling line segment S with the smaller radius of curvature of each arc surface 426 is matched to greatly push the sliding plate 423 to generate a larger initial thrust, thereby increasing the The clamping force of the drive disk assembly 42 achieves a quick start and improves the speed change responsiveness. When the present embodiment reaches a medium speed or a high speed, the rolling line segment S with the larger radius of curvature of each arc surface 426 is matched, so as to ease the movement of the sliding plate 423 and have a more appropriate acceleration performance, and can reduce the wear of components and fuel consumption, which in turn increases durability.

另外需要说明的是,由于本实施例的该轴距W较市面上产品短,不仅能匹配大功率比的机种,还能据此缩小该驱动机构3与该变速机构4的尺寸,进而达到车辆轻量化及提升空间紧致性的功效。再者,由于该变速机构4紧致化的原因,便能缩短车辆的前后轮轴距,使得车辆的回转半径缩短,借此提升操控性而使车辆操控上较灵活。此外,由于本实施例的该驱动机构3与该摇臂机构5之间的设置方式,使得连接该后车轮6的悬吊系统(图未示)仅需要负荷该摇臂机构5及该后车轮6的负重即可,因而能提升骑乘感及操作性。In addition, it should be noted that, because the wheelbase W of this embodiment is shorter than that of the products on the market, it can not only match the models with high power ratio, but also reduce the size of the drive mechanism 3 and the speed change mechanism 4 accordingly, so as to achieve The effect of reducing vehicle weight and improving space compactness. Furthermore, due to the compactness of the transmission mechanism 4, the wheelbase of the front and rear wheels of the vehicle can be shortened, so that the turning radius of the vehicle can be shortened, thereby improving the maneuverability and making the vehicle more flexible. In addition, due to the arrangement between the drive mechanism 3 and the rocker mechanism 5 in this embodiment, the suspension system (not shown) connecting the rear wheel 6 only needs to load the rocker mechanism 5 and the rear wheel The load of 6 is sufficient, so the riding feeling and operability can be improved.

综上所述,本实用新型变速机构及具有变速机构的摩托车,借由每一个弧面426具有多个不同曲率半径的滚动线段S的结构设计,借此提供不同的变速能力,不仅能配合高速档位与低速档位的加速需求,还能克服该轴距W变小所衍生的的问题,达成轻量化,并进一步地提升车辆的空间紧致性,故确实能达成本实用新型的目的。To sum up, the speed change mechanism and the motorcycle with the speed change mechanism of the present invention provide different speed changing capabilities by virtue of the structural design that each arc surface 426 has a plurality of rolling line segments S with different curvature radii. The acceleration requirements of high-speed gears and low-speed gears can also overcome the problems caused by the smaller wheelbase W, achieve light weight, and further improve the space compactness of the vehicle, so it can indeed achieve the purpose of this utility model. .
